| Frequent coal mine accidents, and seriously affected the normal production order and the safety of the lives of staff, it shows all the more mine safety information system for the importance of production safety in coal mines.Mine Safety existing information systems industry is mostly based on a bus wired communication transmission networks. But with coal mining and excavation of the pipeline extension, pure cable networks exist coverage, scalability, flexibility, such as the insufficient to meet the needs of production safety. In order to better address this problem, in recent years, wireless personal area network (wireless personal area network, or WPAN) technology gradually developed, we have to solve the problem provided a new way of thinking. WPAN to close within the scope of equipment to establish a wireless connection to within a few metres of multiple devices through wireless link so that they can communicate with each other and even access the Internet or LAN.ZigBee technology, as a recently emerging WPAN communications technology, the agreement with a simple, low cost, low power consumption, easy to network characteristics such as a home system control, building automation, industrial monitoring the area has a broad market space.Based on ZigBee technology-based, in view of the actual demand for coal mine safety environment of the wireless network in coal mine safety system, the application of the study; the basic algorithm and the network of underground roadway characteristics of the distribution of the algorithm in the practical application carried out a number of improvements to further enhance the original algorithm of network performance; the establishment of the network, such as the addition of nodes process research. Detailed description of the equipment in the establishment of networks, join the network on specific issues such as the treatment process. And their own mine safety information systems, using a wired and wireless network with a combination of network, and expanded coal mine safety system control of the whole information system scalability, and flexibility to enhance the information collection.In this paper, the content of which is the main research company KJ293 the High-Tech System of wireless transceiver module for upgrading based on the completion of the research network functions, this article will continue to base the needs of wireless network on the existing wireless transceiver letter of the machine is given a complete design of the hardware and software flow chart and complete the entire design. |
